Shangma Thermal Power Project Must Be Coordinated With Smog Management

- Oct 21, 2018-

Under the energy structure that relies heavily on coal-fired power, the new Shangma Power Plant is bound to bring a lot of environmental concerns to the public. In contrast, if the wind, water and solar energy stored in Guangdong can be used well, perhaps the project will be evaluated and There will be a lot less controversy on the horse.

A few days ago, according to media reports, the Ministry of Environmental Protection is accepting environmental impact assessment reports for three large coal-fired power plants in Guangdong. Two of Guangdong Province are “upper-down” projects, and one in Yuedong is a new construction. The newly installed coal-fired power plant has a total installed capacity of 5.32 million kilowatts, replacing 1.94 million kilowatts of small thermal power, and burning 12.64 million tons of coal per year. All three power plants are scheduled to start production in 2015-2016. According to the EIA report, the implementation of “upper and smaller pressure” in coal-fired power plants is conducive to the reduction of major atmospheric pollutants, which is conducive to alleviating the environmental pressure in the Pearl River Delta region, but there is still some controversy.

For people living in the smoggy age, seeing three thermal power plant projects almost simultaneously, heart anxiety is an extremely normal reaction. Although the Pearl River Delta region where the three power plants are located is not the most smog area in China, the rising number of haze days and pollution index have made people in the most active areas of the Chinese economy feel the serious threat of haze itself. Therefore, once the general public is told to build a coal-fired power plant, heart-to-life rejection is a universal response.

However, as pointed out in the EIA report, the two power plants have implemented the “big and small” plan, which is to shut down some small thermal power units at the same time as the construction of large-capacity, high-parameter, low-consumption and low-emission units. Therefore, in general, the sulfur dioxide, nitrogen oxides and soot emitted by coal-fired power plants will indeed be cut. Therefore, in the context of the continuous increase in electricity consumption in the Pearl River Delta region, the selection of large-capacity units with higher installation efficiency and lower emissions is indeed a coordinated path.

However, only two of the three power plants have a “big and small” plan. The 2×1000M W of the Jiahuwan Power Plant in Lufeng, Guangdong is a new coal-fired unit, which means that in total, coal-fired power generation It is still growing in Guangdong. As we all know, China is the world's largest coal consumer, and according to the China Energy Statistical Yearbook 2012, Guangdong's coal consumption ranked seventh in the country in 2011. And at the time of reporting, the media often used Guangdong to compare the national coal consumption of Australia to illustrate the huge consumption of coal in Guangdong. In addition, it needs to be supplemented that, unlike the national coal consumption of 50% for power generation, more than 65% of coal consumption in Guangdong is used for coal power, and coal-fired power generation accounts for about 80% of Guangdong's power generation.

The above data shows that the existing energy structure in Guangdong is very dependent on coal-fired power, which is obviously not good news for the smog treatment project. Although the Ministry of Environmental Protection promulgated the "Emission Standards for Thermal Pollutants in Thermal Power Plants" issued in 2011, its severity is the highest in the world. The "Standards" require that before July 1, 2014, the existing power plants should carry out all-round environmental protection technology transformation. That is to say, the thermal power industry needs to complete technical upgrading in terms of dust removal, desulfurization and efficiency reduction, and denitrification. However, as long as the existing energy structure does not change significantly, the impact of coal-fired power generation on air pollution must be heavyweight.

What needs to be more clear is that the air pollution problem generated by thermal power projects does not only reside locally. Similar to almost all environmental problems, the boundary of smog influence is uncontrollable. As Dong Wen, a professor at the Department of Chemistry and Chemical Engineering at Guangzhou University, pointed out, the Guangdong-East Malaysian thermal power project will also affect the air quality of the Pearl River Delta. "Air is mobile, especially in coastal areas. Air pollution is reversible at any time and will definitely affect Guangdong. The total installed capacity will increase, and the pollutants emitted will definitely increase.” Therefore, the launch of the three power plants seems to cast a shadow over the prospects for air improvement in the Pearl River Delta region.

In the context of revitalizing Guangdong's east and west, the contradiction between economic development and environmental protection has always been the main line to test the ruling party. As the coordinator of the relationship between the two, if the local government needs to carry more pressure from economic growth, then the high-cost downsizing of the thermal power plant may be put on hold. Similar examples have been commonplace in the past, owing to the lack of a strong enough and severe regulator. Therefore, under the energy structure that relies heavily on coal-fired power, the new Shangma Power Plant is bound to bring a lot of environmental concerns to the public. In contrast, if the wind, water and solar energy stored in Guangdong can be used well, perhaps the project The EIA and the disputes will be much less.
